Jersey rockers the Gaslight Anthem, reggae-tinged festival faves Michael Franti & Spearhead and electronic duo Big Gigantic are among the artists that have been added to the lineup of Mountain Jam 2013, scheduled for June 6 through 9 at the Hunter Mountain ski resort in Hunter, N.Y.

Conspirator -- a side project of Disco Biscuits keyboardist and bass player Aron Magner and Marc Brownstein -- have been added as late-night entertainment, along with White Denim, Soulive with the Shady Horns and Holy Ghost, who'll hop on the decks for a DJ set.

"Pretty Early" prices -- which are up to 20 percent lower than day-of prices -- are currently available for 4-Day, 3-Day and VIP Passes to Mountain Jam, and all three options are available with and without camping. Also available this year for the first time is the Super VIP Pass, which gets you catered meals, free massages and meet-and-greets with the artists.
